I don't have actually any way to know the date of the earliest message (because we can't search thread only by date, hopfully it will be fixed in a new version of WBB3), but when I make a search with a common word (bonj* for example), the earliest message date from 2005, the good date.

But if I do a counter update, the installation date is still set to 1975.

Someone told me this problem will be fixed in a next version, but will it be fixed also for the migrations already made?

Guiwald, since u r in deseperate need to fix ill tell u how to modify the database directly:run the following sql command and ull get the correct date:UPDATE `XXXXXXXX`.`wbb1_1_thread` SET `time` = '1213185804' WHERE `wbb1_1_thread`.`time` ='0'Don't forget to change XXXXX by your database namelet me know if you need further help
